PREREQUISITES
Basic course in soil mechanics including soil physics and basic soil behavior. Stress-strain relationships in soils. Mean stresses and deviatoric stresses. Effective stress concept and consolidation theory. Bearing capacity. Classical consolidation theory and settlement calculation. Earth pressure against retaining walls. Slope stability with cylindrical slip surface. Common laboratory methods.

COURSE AIM
To provide a deeper understanding of some areas of soil mechanics and foundation engineering and to introduce the student to ongoing research in some areas of soil mechanics. A number of subjects well aimed for student final project work are also introduced. Further, the intention is to train the student's capability of finding information and to present it in the form of a small research paper.

CONTENTS
Stress-strain relationships for soils and constitutive models (30%) Methods for determination of stress/strain relationships in soils. Soil behavior under different loading conditions. The basics of the Critical-State theory. Different concepts for modeling soil behavior under loading, based upon the theory of plasticity. Lab with use of triaxial apparatus for determination of strength characteristics of soil. Heat transfer mechanisms and frost action in soils (30%) Methods for determination of thermal properties of soil. Derivation and calculation of frost front propagation by using the "Neumann equation". Frost susceptibility (classification). Ice lens formation. Frost heave. Unfrozen water in frozen soil. Models for calculation of frost heave in a freezing soil. Strength of frozen soil. Artificial freezing of ground. Permafrost and its technical and economical consequences. Slope stability. Classical and numerical calculation methods (20%). Some aspects on soft-ware for solving soil mechanic problems. Application by analyzing some slope stability problems with different types of computer programs. Lab. Assignment. Soil reinforcement (20%) Basic theories for soil reinforcement. Geotextiles and geosynthetics. Design procedure and examples.

TEACHING
Teaching is given in classes, including problem-solving and informal discussions. Laboratory work. Assignments solved individually by the students. Writing and presenting a research paper. Oral presentation.
